Phenolic resin filter element for petrochemical refining

The Zilaiquan filter element adopts a unique two-stage filtration design, which can maximize the removal of particulate matter when handling viscous substances, organic solvents, and high-temperature fluids, and effectively extend its service life. The external spiral pre-filter winding structure enhances the strength of the filter element and avoids the problem of debris residue commonly found in traditional machined resin-bonded filter elements, ensuring a cleaner filtration process. The Zilaiquan filter element uses a non-bonding process and supports production in various specifications.
Conventional lengths include 10″, 20″, 30″, 40″, and 50″, with a diameter of 63±1mm (any length within 50 inches can be customized as required).
This filter element can provide nine different particle filtration accuracies with pore sizes of 1 – 2μm, 5μm, 10μm, 25μm, 50μm, 75μm, 125μm, 150μm, and 200μm to meet the needs of various industrial applications.
Application areas:

Structural features:
• External spiral winding: The outer spiral winding helps to collect large-particle contaminants, while the inner layer precisely controls and filters particles of the rated size.
• Enhanced surface area: The external winding increases the surface area of the filter element, improves filtration efficiency, effectively eliminates loose debris commonly found in machined products, and reduces the risk of contamination.
• Enhanced strength and fracture resistance: The use of an ultra-long acrylic fiber structure provides greater strength, fracture resistance, and anti-migration properties, avoiding the common problem of particle shedding in the so-called “short fiber” grooved fiber filter elements on the market.
• Customized design: Special ends, plugs, dimensions, etc. can be customized according to the specific needs of users to meet different process and environmental requirements.
• Phenolic resin impregnation: The impregnation of phenolic resin strengthens the structure of the filter element, making it suitable for filtering fluids with a viscosity of up to 15,000 SSU (3200 cks).
• High pressure-bearing capacity: The filter element can withstand pressure fluctuations of up to 150 psid (depending on the fluid temperature), ensuring stable operation under high-pressure conditions.
• Monolithic structure: The monolithic design eliminates the bypass problem of multi-length filter elements, simplifies the replacement process, and improves ease of use.
• Silicon-free structure: The silicon-free structure design ensures zero pollution and avoids negatively affecting the bonding performance of handicrafts such as coatings. The Zilaiquan wound resin-bonded filter element, with its excellent design and outstanding performance, is an ideal choice in the liquid filtration process of various industries, providing users with efficient, stable, and long-lasting filtration solutions.
